Solution for 1/2x^2+3/8x=2 equation: 


x in (-oo:+oo)

(1/2)*x^2+(3/8)*x = 2 // - 2

(1/2)*x^2+(3/8)*x-2 = 0

1/2*x^2+3/8*x-2 = 0

DELTA = (3/8)^2-(-2*1/2*4)

DELTA = 265/64

DELTA > 0

x = ((265/64)^(1/2)-3/8)/(1/2*2) or x = (-(265/64)^(1/2)-3/8)/(1/2*2)

x = (265/64)^(1/2)-3/8 or x = -((265/64)^(1/2)+3/8)

x in { -((265/64)^(1/2)+3/8), (265/64)^(1/2)-3/8 }
